    The Olig Sand Reservoirs, classified as part of the Shallow Oil Zone, were studied and evaluated. The reservoirs are located in Section 30R, T30S, R23E and Section 24Z, T30S, R22E, M.D.B. and M., all in Elk Hills Oil Field, Naval Petroleum Reserve No. 1, Kern County, California. The three productive reservoirs studied cover an area of 255 acres, and originally contained 3311 MMCF of gas condensate in 4292 acre-feet of sand. The main reservoir, Fault Block I in Section 30R, has been on production since 1982 and is largely depleted. The reservoirs around wells 324-30R and 385-24Z should still be in a virgin state. They can be depleted either through those wells, when their service as Stevens Zone producers is completed, or by twin well replacements drilled specifically as Olig Sand completions. Thirty-six exhibits have been included to present basic data and study results in a manner that will enhance the readers's understanding of the reservoirs. These exhibits include six maps in the M-series, six sections in the S-Series, and fourteen figures in the F-Series, as well as ten tables. The Appendix includes miscellaneous basic data such as well logs, core analyses, pressure measurements, and well tests. The Calculations Section of the report develops and explains the analytical methods used to define well productivity, determine reserves, and schedule future production of those reserves. Although no MER recommendations have been made for these gas condensate reservoirs, recommended depletion schemes and schedules are presented. These schemes include one eventual recompletion and one new well to maximize present worth of these reservoirs which carry proved reserves of 289 MMCF and probable reserves of 853 MMCF, effective August 1, 1986. In addition, potential future testing is earmarked for wells 322-30R and 344-30R. 11 refs., 14 figs., 10 tabs.

    This report documents the development of constitutive material models for the overburden formations, reservoir formations, and underlying strata at the Lost Hills oil field located about 45 miles northwest of Bakersfield in Kern County, California. Triaxial rock mechanics tests were performed on specimens prepared from cores recovered from the Lost Hills field, and included measurements of axial and radial stresses and strains under different load paths. The tested intervals comprise diatomaceous sands of the Etchegoin Formation and several diatomite types of the Belridge Diatomite Member of the Monterey Formation, including cycles both above and below the diagenetic phase boundary between opal-A and opal-CT. The laboratory data are used to drive constitutive parameters for the Extended Sandler-Rubin (ESR) cap model that is implemented in Sandia's structural mechanics finite element code JAS3D. Available data in the literature are also used to derive ESR shear failure parameters for overburden formations. The material models are being used in large-scale three-dimensional geomechanical simulations of the reservoir behavior during primary and secondary recovery.

    The general Reservoir Study of the Western Shallow Oil Zone was prepared by Evans, Carey and Crozier as Task Assignment 009 with the United States Department of Energy. The study addresses the Bittium Wilhelm, Gusher, and Calitroleum Sands and their several sub units and pools. A total of twenty-eight (28) separate reservoir units have been identified and analyzed. Areally, these reservoirs are located in 31 separate sections of land including and lying northwest of sections 5G, 8G, and 32S, all in the Elk Hills Oil Fileds, Naval Petroleum Reserve No. 1, Kern County California. Vertically, the reservoirs occur as shallow as 2600 feet and as deep as 4400 feet. Underlying a composite productive area of about 8300 acres, the reservoirs originally contained an estimated 138,022,000 stock tank barrels of oil, and 85,000 MMCF of gas, 6300 MMCF of which occurred as free gas in the Bittium and W-1B Sands. Since original discovery in April 1919, a total of over 500 wells have been drilled into or through the zones, 120 of which were completed as Western Shallow Oil Zone producers. Currently, these wells are producing about 2452 barrels of oil per day, 1135 barrels of water per day and 5119 MCF of gas per day from the collective reservoirs. Basic pressure, production and assorted technical data were provided by the US Department of Energy staff at Elk Hills. These data were accepted as furnished with no attempt being made by Evans, Carey and Crozier for independent vertification. This study has successfully identified the size and location of all commercially productive pools in the Western Shallow Oil Zone. It has identified the petrophysical properties and the past productive performance of the reservoirs.

    The Big Hill SPR facility located in Jefferson County, Texas has been a permitted operating crude oil storage site since 1986 with benign environmental impacts. However, Congress has not authorized crude oil purchases for the SPR since 1990, and six storage caverns at Big Hill are underutilized with 70 million barrels of available storage capacity. On February 17, 1999, the Secretary of Energy offered the 70 million barrels of available storage at Big Hill for commercial use. Interested commercial users would enter into storage contracts with DOE, and DOE would receive crude oil in lieu of dollars as rental fees. The site could potentially began to receive commercial oil in May 1999. This Environmental Assessment identified environmental changes that potentially would affect water usage, power usage, and air emissions. However, as the assessment indicates, changes would not occur to a major degree affecting the environment and no long-term short-term, cumulative or irreversible impacts have been identified.

    A method for treating a tar sands formation includes providing heat to at least part of a hydrocarbon layer in the formation from a plurality of heaters located in the formation. The heat is allowed to transfer from the heaters to at least a portion of the formation. A viscosity of one or more zones of the hydrocarbon layer is assessed. The heating rates in the zones are varied based on the assessed viscosities. The heating rate in a first zone of the formation is greater than the heating rate in a second zone of the formation if the viscosity in the first zone is greater than the viscosity in the second zone. Fluids are produced from the formation through the production wells.

    In 1978, the water cleaning system for the KE Basin was upgraded by adding a sand filter and ion exchange columns. Basin water containing finely divided solids is collected by three surface skimmers and pumped to the sand filter. Filtrate from the sand filter is further treated in the ion exchange modules. The suspended solids accumulate in the sand until the pressure drop across the filter reaches established operating limits, at which time the sand filter is backwashed. The backwash is collected in the NLOP, where the solids are allowed to settle as sludge. Figure 2-1 shows a basic piping and instrumentation diagram depicting the relationship among the basin skimmers, sand filter, and NLOP. During the course of deactivation and decommissioning (D&D) of the K-Basins, the sand filter and its media will need to be dispositioned. The isotopic distribution of the sludge in the sand filter has been estimated in KE Basin Sand Filter Monolith DQO (KBC-24705). This document estimates the sand filter contribution to the KE hazard categorization using the data from the DQO.

    The tar-sand resources of the US have the potential to yield as much as 36 billion barrels (bbls) of oil. The tar-sand petroleum-extraction technologies now being considered for commercialization in the United States include both surface (above ground) systems and in situ (underground) procedures. The surface systems currently receiving the most attention include: (1) thermal decomposition processes (retorting); (2) suspension methods (solvent extraction); and (3) washing techniques (water separation). Underground bitumen extraction techniques now being field tested are: (1) in situ combustion; and (2) in situ steam-injection procedures. At this time, any commercial tar-sand facility in the US will have to comply with at least 7 major federal regulations in addition to state regulations; building, electrical, and fire codes; and petroleum-industry construction standards. Pollution-control methods needed by tar-sand technologies to comply with regulatory standards and to protect air, land, and water quality will probably be similar to those already proposed for commercial oil-shale systems. The costs of these systems could range from about $1.20 to $2.45 per barrel of oil produced. Estimates of potential pollution-emisson levels affecting land, air, and water were calculated from available data related to current surface and in situ tar-sand field experiments in the US. These data were then extrapolated to determine pollutant levels expected from conceptual commercial surface and in situ facilities producing 20,000 bbl/d. The likelihood-of-occurrence of these impacts was then assessed. Experience from other industries, including information concerning health and ecosystem damage from air pollutants, measurements of ground-water transport of organic pollutants, and the effectiveness of environmental-control technologies was used to make this assessment.

    Bentonite-Sand Backfill is a part of Engineered Barrier System (EBS) widely used in a Near Surface Disposal Facility (NSDF) to delay migration of radionuclides from the disposed nuclear waste in a geo environment. Laboratory migration experiments have been conducted to understand the advection/diffusion mechanisms of various radionuclides through backfill and to evaluate their migration rates in order to assess the performance of EBS. Migration through backfill is an extremely slow process and the experiments are time consuming. Also, these experiments have limitations to simulate the field stress conditions. Various researchers have experienced the advantages of centrifuge modeling technique to model contaminant transport problems of geo-environment. However, no such studies have been carried out adopting this technique to model the behaviour of bentonite-sand mixture as backfill in NSDF. An attempt has been made in the present study to investigate the validity of this technique to carry out such studies. Significance of geotechnical centrifuge modeling to simulate the prototype radionuclide migration mechanisms through backfill is highlighted. This paper presents the dimensional analysis of various scale factors to construct a physical model for centrifuge tests to monitor online the migration phenomena of radionuclides through bentonite-sand mixture. Studies reveal the feasibility of the technique to evaluate the migration parameters in a short experimental duration. Such studies help in improving EBS design and assessing the long-term performance of EBS in NSDF. (authors)

    A habitat based assessment was conducted of the US Army Corps of Engineers' Hills Creek Dam and Reservoir Project on the Middle Fork Willamette River, Oregon, to determine losses or gains resulting from the development and operation of the hydroelectric related components of the project. Preconstruction, postconstruction, and recent vegetation cover types of the project site were mapped based on aerial photographs from 1944, 1964, and 1979, respectively. Vegetation cover types were identified within the affected area and acreages of each type at each period were determined. Fifteen wildlife target species were selected to represent a cross-section of species groups affected by the project. An interagency team evaluated the suitability of the habitat to support the target species at each time period. An evaluation procedure which accounted for both the quantity and quality of habitat was used to aid in assessing impacts resulting from the project. The Hills Creek Project extensively altered or affected 4662 acres of land and river in the Middle Fork Willamette River drainage. Impacts to wildlife centered around the loss of 2694 acres of old-growth forest and 207 acres of riparian habitat. Impacts resulting from the Hills Creek Project included the loss of winter range for Roosevelt elk, and the loss of year-round habitat for black-tailed deer, black bear, cougar, river otter, beaver, ruffed grouse, spotted owl, and other nongame species. Bald eagle and osprey were benefited by an increase in foraging habitat. The potential of the affected area to support wildlife was greatly altered as a result of the Hills Creek Project, losses or gains in the potential of the habitat to support wildlife will exist over the life of the project.

    This report represents an extension of previous findings concerning the status of the endangered species, Crotaphytus silus (blunt-nosed leopard lizard) on the Naval Petroleum Reserve Number 1 (NPR-1), Elk Hills, California. Previous findings in 1979 were limited to superficial observations of the occurrence and distribution of C. silus on NPR-1. The present report details findings from more extensive field work conducted from late May to early August 1980, and complements the 1979 work. The ultimate purpose of the investigations reported here is to provide sufficient bases for making informed decisions concerning the relationships of present and possible future oil-related activities at Elk Hills to the status of C. silus. There have been no particularly unique life history indicators of environmental impact on C. silus mediated through activities on NPR-1. Observations may be made, however, on the seasonal correlates of such activities: (1) individual C. silus may be buried or fatally exposed to the environment by construction activities occurring during the species' hibernation; (2) during periods when adult C. silus is active on the surface, construction activities may displace individuals that may not then be able to successfully occupy a new range, although it is to be noted in this regard that the home range of the species can be rather plastic; (3) construction activities bury or expose nest chambers of C. silus. This would unfavorably affect an average of three potential hatchlings with each burial or exposure; and (4) construction occurring when only (or predominantly) hatchlings are active on the surface may affect animals less able to avoid these activities than adults. In addition, hibernating adults will be affected, as previously noted.

    DOE proposes to conduct a variety of post-sale site remediation activities, such as characterization, assessment, clean-up, and formal closure, at a number of inactive waste sites located at Elk Hills. The proposed post-sale site remediation activities, which would be conducted primarily in developed portions of the oil field, currently are expected to include clean-up of three basic categories of waste sites: (1) nonhazardous solid waste surface trash scatters, (2) produced wastewater sumps, and (3) small solid waste landfills. Additionally, a limited number of other inactive waste sites, which cannot be typified under any of these three categories, have been identified as requiring remediation. Table 2.1-1 presents a summary, organized by waste site category, of the inactive waste sites that require remediation per the PSA, the ASA, and/or the UPCTA. The majority of these sites are known to contain no hazardous waste. However, one of the surface scatter sites (2G) contains an area of burn ash with hazardous levels of lead and zinc, another surface scatter site (25S) contains an area with hazardous levels of lead, a produced wastewater sump site (23S) and a landfill (42-36S) are known to contain hazardous levels of arsenic, and some sites have not yet been characterized. Furthermore, additional types of sites could be discovered. For example, given the nature of oil field operations, sites resulting from either spills or leaks of hazardous materials could be discovered. Given the nature of the agreements entered into by DOE regarding the required post-sale clean-up of the inactive waste sites at Elk Hills, the Proposed Action is the primary course of action considered in this EA. The obligatory remediation activities included in the Proposed Action are standard procedures such that possible variations of the Proposed Action would not vary substantially enough to require designation as a separate, reasonable alternative. Thus, the No Action Alternative is the only other option considered in this EA.

    Research on tar sand is briefly discussed. The research program supported by the US Department of Energy (DOE) includes a variety of surface extraction schemes. The University of Utah has process development units (PDU) employing fluidized bed, hot, water-assisted, and fluidized-bed/heat-pipe, coupled combustor technology. Considerable process variable test data have been gathered on these systems: (1) a rotary kiln unit has been built recently; (2) solvent extraction processing is being examined; and (3) an advanced hydrogenation upgrading scheme (hydropyrolysis) has been developed. The University of Arkansas, in collaboration with Diversified Petroleum, Inc., has been working on a fatty acid, solvent extraction process. Oleic acid is the solvent/surfactant. Solvent is recovered by adjusting processing fluid concentrations to separate without expensive operations. Western Research Institute has a PDU-scale scheme called the Recycle Oil Pyrolysis and Extraction (ROPE) process, which combines solvent (hot recycle bitumen) and pyrolytic extraction. 14 refs., 19 figs.

    Over 500 wells, including wells producing from the deeper Miocene Stevens sands, penetrate the Western Shallow Oil Zone (Pliocene Etchegoin Formation) at the Elk Hills Naval Petroleum Reserve in California. The Western Shallow Oil Zone Gusher and Calitroleum sands are very fine grained, silty and pyritic and are interbedded with silty shales. Electric logs generally show 1[1/2]-2[1/2] ohm-meters of deep resistivity and the spontaneous potential displays little or no response to the sands. However, approximately 180 wells in each of the mapped productive sands have sidewall sample data to visually inspect the rock for hydrocarbons. Each productive interval within the Western Shallow Oil Zone has two or more pools. The most exploited (and most heavily drilled) of these pools is at the western end of the Eastern anticline. The pools on the Western anticline have few tests and production is limited and generally commingled. In order to identify productive intervals and to delineate the areal extent of these sands, qualitative assessment of sidewall sample data was done and maps of log permeability times oil saturation were prepared for each zone. The analysis showed large amounts of unexploited hydrocarbons in the Western pools. Complete exploitation of the Gusher and Calitroleum sands will recover in excess of 11 million additional barrels of 38 degree gravity oil.

Complete exploitation of the Gusher and Calitroleum sands will recover in excess of 11 million additional barrels of 38 degree gravity oil.

    Growth of subsea anticlines during deposition of the upper Miocene 24Z and 26R sandstones at Elk Hills caused the development of several sinuous, lenticular sand bodies. later structural growth enhanced the trap characteristics of these sandstones. Both sandstones are in the uppermost portion of the Elk Hills Shale Member of the Monterey Formation and contain channel-fill and overbank deposits of sand-rich turbidite systems. At the onset of turbidite deposition, low relief subsea anticlines separated broad basins which progressively deepened to the northeast. Channel-fill deposits of coarse-grained sand generally followed the axes of these northwest-southeast-trending basins. At several sites, channel-fill deposits also spilled north across anticlinal axes into the next lower basins. Wide bands of overbank sand and mud were deposited at sand body edges on the flat basin floors. Midway through turbidite deposition, a period of anticlinal growth substantially raised subsea relief. Channel-fill deposits continued in narrower basins but passed north into deeper basin only around well-defined sites at the anticlines' downplunge termini. Narrow basin shapes and higher anticline relief prevented significant overbank deposition. With Pliocene to Holocene uplift of the late Miocene structural trends, stratigraphic mounding of the north-directed channel-fill deposits helped create structural domes at 24Z, 2B and Northwest Stevens pools. In sand bodies lacking significant overbank deposits prevented oil entrapment in sand bodies deposited at times of low anticlinal relief.

    A detailed depositional model for the uppermost sand reservoirs of the Stevens Oil Zone, Elk Hills Field, California, contains three facies: turbidite channel-fill sand bodies, overbank Sandstone and mudstone, and pelagic and hemipelagic siliceous shale. Sand bodies are the primary producing facies and consist of layered, graded sandstone with good permeability. The presence of incipient anticlines with subsea relief in the late Miocene resulted in deposition of lenticular and sinuous sand Was within structurally created channels. Relief of these structural channels was low when the earliest sand bodies were deposited, leading to a wide channel complex bounded by broad overbank deposits of moderate to low permeability. As deposition proceeded, increased structural relief constrained the channels, resulting in narrower sand body width and relatively abrupt channel terminations against very low permeability siliceous shale. With post-Miocene uplift and differential compaction, stratigraphic mounding of sand bodies helped create structural domes such as the 24Z reservoir. Stratigraphic traps including the 26R reservoir were also created. Such traps vary in seal quality from very effective to leaky, depending on the lateral transition from sand bodies to siliceous shale. Application of the Elk Hills turbidity model (1) provides a framework for monitoring production performance in the 24Z and Northwest Stevens waterflood projects; and for tracking gas migration into and out of the 26R reservoir, (2) helps b identify undeveloped locations in the 26R reservoir ideally suited for horizontal wells, (3) has led to the identification of two new production trends in the 29R area, and (4) makes possible the development of exploration plays in western Elk Hills.

    In 1988 the US Department of Energy and Bechtel implemented a program to slow production declines in the Elk Hills 26R pool sand of the Naval Petroleum Reserve No. 1. It was also hoped horizontal wells would increase the production rate, decrease gas production and extend economic life of the reservoir. The Stevens sand pool targeted for the project is a high-quality, sand-rich turbidite channel system encapsulated within Miocene Monterey siliceous shales, mudstones and associated sediments. The pool is about 3-miles long by 3/4-mile wide. The paper describes the specifications and drilling of the first four out of the 14 horizontal wells drilled at this facility. Horizontal drilling technology has completely altered the future of the 26R pool. In 1980 estimated ultimate recovery (EUR) from the sand was 211 million bbl. With the latest horizontal well drilling campaign, the pool is expected to pass that estimate in 1997 when oil production is forecasted to be at least 13,000 b/d. EUR form the 26R sand now is more than 250 million bbl, and even that estimate is being revised upward.

    The US Department of Energy proposes to develop a limited enhanced oil recovery project in the Shallow Oil Zone at Naval Petroleum Reserve No. 1 (NPR-1) Elk Hills. The project would employ steam forced into the oil-bearing formation through injector wells, and would involve two phases. The initiation of the second phase would be dependent on the economic success of the first phase. The total project would require the drilling of 22 new wells in a 45-acre area supporting seven existing production wells. It would also require construction of various surface facilities including a tank setting (gas-oil separation system), steam generators, and a water treatment plant. Adverse environmental impacts associated with the proposed steam flood project would include the effects on vegetation, wildlife and land-use resulting from the total reconfiguration of the topography within the project bondaries. Other adverse impacts include the emission of oxides of nitrogen, carbon monoxide, hydrocarbons and particulates from steam generators, vehicles and associated surface facilities. Minor adverse impacts include localized noise and dust during constuction, and reduction of visual quality. 48 refs., 7 figs., 10 tabs.

    The oil reserves at Elk Hills field, California, are listed as amounting to 835 million bbl. There is 12 times that amount lying in shallow sands in the San Joaquin Valley, although the oil is much heavier and requires more refining before use. Improved recovery techniques have enabled higher rates of recovery for heavy oil than in the past. Some of these techniques are described, including bottom-hole heating, steam injection, and oil mining. Bottom-hole heating alone raised recovery rates for heavy oil to 25%, and steam injection raised rates to 50%. It is predicted that oil mining may be able to accomplish 100% recovery of the heavy oil.

    Surveys to determine the distribution and relative abundance of blunt-nosed leopard lizards on Naval Petroleum Reserve-1 were conducted in 1980 and 1981. In 1982 radiotelemetry and pitfall trapping techniques were used to gain additional information on the species and develop alternative methods of study. Incidental observations of blunt-nosed leopard lizards were recorded and used in the distribution information for NPR-1. DOE determined during this biological assessment that the construction projects and operational activities necessary to achieve and sustain MER have not adversely affected the blunt-nosed leopard lizard and its habitat, because only approximately 6% of the potential blunt-nosed leopard lizard habitat on NPR-1 was disturbed by construction and operational activities. DOE believes that the direct, indirect, and cumulative effects of MER will not jeopardize the continued existence of the species, because results of surveys indicated that blunt-nosed leopard lizards are mainly distributed near the periphery of Elk Hills where few petroleum developments occurred in the past and where they are unlikely to occur in the future. A policy of conducting preconstruction surveys to protect blunt-nosed leopard lizard habitat was initiated, a habitat restoration plan was developed and implemented, and administrative policies to reduce vehicle speeds, contain oil spills, restrict off-road vehicle (ORV) travel, and to prohibit public access, livestock grazing, and agricultural activities were maintained.

    We calculate the power spectrum of curvature perturbations when the inflaton field is rolling over the top of a local maximum of a potential. We show that the evolution of the field can be decomposed into a late-time attractor, which is identified as the slow roll solution, plus a rapidly decaying non-slow roll solution, corresponding to the field rolling ``up the hill'' to the maximum of the potential. The exponentially decaying transient solution can map to an observationally relevant range of scales because the universe is also expanding exponentially. We consider the two branches separately and we find that they are related through a simple transformation of the slow roll parameter $\\eta$ and they predict identical power spectra. We generalize this approach to the case where the inflaton field is described by both branches simultaneously and find that the mode equation can be solved exactly at all times. Even though the slow roll parameter $\\eta$ is evolving rapidly during the transition from the transient solution to the late-time attractor solution, the resultant power spectrum is an exact power-law spectrum. Such solutions may be useful for model-building on the string landscape.

  11. Study of Reservoir Heterogencities and Structural Features Affecting Production in the Shallow Oil Zone, Eastern Elk Hills Area, California

    Late Neogene (Plio-Pleistocene) shallow marine strata of the western Bakersfield Arch and Elk Hills produce hydrocarbons from several different reservoirs. This project focuses on the shallow marine deposits of the Gusher and Calitroleum reservoirs in the Lower Shallow Oil Zone (LSOZ). In the eastern part of the study area on the Bakersfield Arch at North and South Coles Levee field and in two wells in easternmost Elk Hills, the LSOZ reservoirs produce dry (predominantly methane) gas. In structurally higher locations in western Elk Hills, the LSOZ produces oil and associated gas. Gas analyses show that gas from the eastern LSOZ is bacterial and formed in place in the reservoirs, whereas gas associated with oil in the western part of the study area is thermogenic and migrated into the sands from deeper in the basin. Regional mapping shows that the gas-bearing LSOZ sands in the Coles Levee and easternmost Elk Hills area are sourced from the Sierra Nevada to the east whereas the oil-bearing sands in western Elk Hills appear to be sourced from the west. The eastern Elk Hills area occupied the basin depocenter, farthest from either source area. As a result, it collected mainly low-permeability offshore shale deposits. This sand-poor depocenter provides an effective barrier to the updip migration of gases from east to west. The role of small, listric normal faults as migration barriers is more ambiguous. Because our gas analyses show that the gas in the eastern LSOZ reservoirs is bacterial, it likely formed in-place near the reservoirs and did not have to migrate far. Therefore, the gas could have been generated after faulting and accumulated within the fault blocks as localized pools. However, bacterial gas is present in both the eastern AND western parts of Elk Hills in the Dry Gas Zone (DGZ) near the top of the stratigraphic section even though the measured fault displacement is greatest in this zone. Bacterial gas is not present in the west in the deeper LSOZ which has less measured fault displacement. The main difference between the DGZ and the LSOZ appears to be the presence of a sandpoor area in the LSOZ in eastern Elk Hills. The lack of permeable migration pathways in this area would not allow eastern bacterial gas to migrate farther updip into western Elk Hills. A similar sand-poor area does not appear to exist in the DGZ but future research may be necessary to verify this.

    For those who support U.S. oil sands development, the Canadian oil sands industry is often identified as a model the U.S. might emulate, yielding financial and energy security benefits. For opponents of domestic oil sands development, the Canadian oil sands experience illustrates the risks that opponents of development believe should deter domestic policymakers from incenting U.S. oil sands development. This report does not seek to evaluate the particular underpinnings of either side of this policy argument, but rather attempts to delve into the question of whether the Canadian experience has relevance as a foundational model for U.S. oil sands development. More specifically, this report seeks to assess whether and how the Canadian oil sands experience might be predictive or instructive in the context of fashioning a framework for a U.S. oil sands industry. In evaluating the implications of these underpinnings for a prospective U.S. oil sands industry, this report concentrates on prospective development of the oil sands deposits found in Utah.

Most current production from the A1-A2 interval comes from well 373A-7R, are completed waterflood wells that came on line in 1992 at 1400 BOPD. Well 373A-7R is an anomaly in the A1-A2 zone, where average production from the other ten wells is 200 BOPD. Other evidence for compartmentalization in the A1-A2 interval includes sporadic oil-water contacts and drawdown pressures, difficult log correlations, and rapid thickness changes. In 1973, well 362-7R penetrated 220 ft of wet Al sand. The well was redrilled updip and successfully completed in the A1, where the oil-water contact is more than 130 ft lower than the original hole and faulting is not apparent. In 1992, horizontal well 323H-7R unexpectedly encountered an entirely wet Al wedge zone. Reevaluation of the A1-A3 and other sands as mass transport origin is important for modeling initialization and production/development strategies.

    The Main Body B reservoir in the Elk Hills Field is a peripherally waterflooded, +400 ft thick series of layered, turbidite Stevens sands. Permeability variation between layers adversely affects the vertical sweep, resulting in production from lower permeability oil sands dominated by production from higher permeability sands. This paper discusses the unique use of various tools to identify water zones to isolate and oil zones to stimulate. Tools used to identify water and oil entry are discussed with respect to their capabilities of identifying oil and water entry into the wellbore.

    Eight horizontal wells have been drilled and completed in a steeply dipping Stevens sand reservoir in the Elk Hills field, Kern County, California. The subject reservoir, called the Stevens 26R, is a turbidite channel sand deposit one mile wide, three miles long, and one mile deep. Formation beds have a gross thickness up to 1,500 feet and dips as high as 60 degrees on the flanks. The original oil column of 1,810 feet has been pulled down to 200 feet by continual production since 1976. The reservoir management operating strategy has been full pressure maintenance by crestal gas injection since 1976. The steep dip of the formation makes gravity drainage the dominant drive mechanism. Additionally, improved recovery is coming from cycling dry gas through the large secondary gas cap region. The prudent placement of the horizontal wells above the oil/water contact promises to improve oil recovery and extend the operating life of the reservoir. Field results are given to compare the performance of the horizontal wells with the conventional wells. The horizontal wells produce at higher rates, lower draw downs, and lower gas/oil ratio which will extend the life of the project and result in higher recovery.

  14. Compressive behavior of fine sand.

    The compressive mechanical response of fine sand is experimentally investigated. The strain rate, initial density, stress state, and moisture level are systematically varied. A Kolsky bar was modified to obtain uniaxial and triaxial compressive response at high strain rates. A controlled loading pulse allows the specimen to acquire stress equilibrium and constant strain-rates. The results show that the compressive response of the fine sand is not sensitive to strain rate under the loading conditions in this study, but significantly dependent on the moisture content, initial density and lateral confinement. Partially saturated sand is more compliant than dry sand. Similar trends were reported in the quasi-static regime for experiments conducted at comparable specimen conditions. The sand becomes stiffer as initial density and/or confinement pressure increases. The sand particle size become smaller after hydrostatic pressure and further smaller after dynamic axial loading.

    The endangered San Joaquin kit fox, Vulpes macrotis mutica, and bluntnosed leopard lizard, Crotaphytus silus, are known to occur on the Elk Hills Naval Petroleum Reserve, NPR-1. An integrated, multiphased field program was designed to gather, synthesize, and interpret ecological information necessary for Biological Assessments required by the Secretary of Interior. These assessments will be used as the basis for a formal consultation with the Department of Interior to determine whether DOE activities on Elk Hills are compatible with the continued existence of the two species. Transects totalling 840 km were walked through all sections of Elk Hills to determine: (1) the presence and relative densities of endangered or threatened species; (2) past and potential impacts of NPR-1 activities on endangered and threatened species; and (3) the potential application of remote sensing for gathering necessary data.

    The West Short Pine Hills field is a shallow gas field that produces from the Shannon Sandstone Member, on the Camp Crook anticline in southwestern Harding County, South Dakota. The Alma McCutchin 1-17 Heikkila discovery was drilled in the NW1/4, Sec. 17, T16N, R2E, to a depth of 1600 ft and completed in October 1977 for 600 MCFGD from perforations at 1405-1411 ft. To date, 40 gas wells have been completed with total estimated reserves of more than 20 bcf. The field encompasses 12,000 ac, with a current drill-site spacing unit of 160 ac. The field boundaries are fairly well defined, except on the south edge of the field. The wells range in depth from 1250 to 2200 ft, and cost $60,000-$85,000 to drill and complete. Core and log analyses indicate that the field has 70 ft of net pay, with average porosity of 30% and average permeability of 114 md. Most wells have been completed with nitrogen-sand frac. Williston Basin Interstate Pipeline Company of Bismarck, North Dakota, operates a compressor station and 2.5 mi of 4-in. line that connects the field to their 160 in. north-south transmission line to the Rapid City area. Currently, producers are netting $1.10-$1.25/million Btu. The late Mathew T. Biggs of Casper, Wyoming, was the geologist responsible for mapping and finding this gas deposit.

    The Dry Gas Zone was defined by US Naval Petroleum Reserve No. 1 Engineering Committee (1957) as ''/hor ellipsis/all sands bearing dry gas above the top of the Lower Scalez marker bed. The term is used to include the stratigraphic interval between the Scalez Sand Zone and the Tulare Formation - the Mya Sand Zone. The reservoirs in this upper zone are thin, lenticular, loosely cemented sandstones with relatively high permeabilities.'' Other than the limited Tulare production in the western part of the field, the Dry Gas Zone is the shallowest productive zone in the Elk Hills Reserve and is not included in the Shallow Oil Zone. It is Pliocene in age and makes up approximately eighty percent of the San Joaquin Formation as is summarized in Exhibit TL-1. The lithologic character of the zone is one of interbedded shales and siltstones with intermittent beds of various thickness sands. The stratigraphic thickness of the Dry Gas Zone ranges from 950 to 1150 feet with a general thickening along the flanks and thinning over the crests of the anticlines. The productive part of the Dry Gas Zone covers portions of 30 sections in an area roughly 10 miles long by 4 miles wide. 4 refs.

  3. Biological assessment of the effects of petroleum production at maximum efficient rate, Naval Petroleum Reserve No. 1 (Elk Hills), Kern County, California, on the endangered San Joaquin kit fox, Vulpes macrotis mutica

    O'Farrell, T.P.; Harris, C.E.; Kato, T.T.; McCue, P.M.

    1986-06-01T23:59:59.000Z

    Between 1980 and 1986 DOE sponsored field studies to gather sufficient information to determine the status of the species on Naval Petroleum Reserve-1 and to evaluate the possible effects of MER. Transect surveys were conducted in 1979 and 1984 to document the distribution and relative density of fox dens. Radiotelemetry studies were initiated to provide information on reproductive success, den use patterns, responses to petroleum field activities, food habits, movement patterns and home ranges, and sources and rates of mortality. Techniques for conducting preconstruction surveys to minimize possible negative effects of MER activities on foxes plus a habitat restoration program were developed and implemented. DOE determined during this biological assessment that the construction projects and operational activities necessary to achieve and sustain MER may have adversely affected the San Joaquin kit fox and its habitat. However, the direct, indirect, and cumulative effects of MER will not jeopardize the continued existence of the species because: (1) results of the extensive field studies did not provide evidence that MER effected negative changes in relative abundance, reproductive success, and dispersal of the species; (2) a successful policy of conducting preconstruction surveys to protect kit fox, their dens, and portions of their habitat was initiated; (3) the Secretary of the Interior did not designate critical habitat; (4) a habitat restoration plan was developed and implemented; (5) a monitoring program was implemented to periodically assess the status of kit fox; (6) a coyote control program was established with FWS to reduce predation on fox; and (7) administrative policies to reduce vehicle speeds, contain oil spills, restrict off-road vehicle (ORV) travel, and to prohibit hunting, trapping, livestock grazing, and agricultural activities, were maintained to protect kit fox.

    The Elk Hills giant oilfield, located in the southern San Joaquin Valley of California, has produced 1.1 billion barrels of oil from Miocene and shallow Pliocene reservoirs. 65% of the current 64,000 BOPD production is from the pressure-supported, deeper Miocene turbidite sands. In the turbidite sands of the 31 S structure, large porosity & permeability variations in the Main Body B and Western 31 S sands cause problems with the efficiency of the waterflooding. These variations have now been quantified and visualized using geostatistics. The end result is a more detailed reservoir characterization for simulation. Traditional reservoir descriptions based on marker correlations, cross-sections and mapping do not provide enough detail to capture the short-scale stratigraphic heterogeneity needed for adequate reservoir simulation. These deterministic descriptions are inadequate to tie with production data as the thinly bedded sand/shale sequences blur into a falsely homogenous picture. By studying the variability of the geologic & petrophysical data vertically within each wellbore and spatially from well to well, a geostatistical reservoir description has been developed. It captures the natural variability of the sands and shales that was lacking from earlier work. These geostatistical studies allow the geologic and petrophysical characteristics to be considered in a probabilistic model. The end-product is a reservoir description that captures the variability of the reservoir sequences and can be used as a more realistic starting point for history matching and reservoir simulation.

    2015-01-01T23:59:59.000Z

    In 'hilltop inflation', inflation takes place when the inflaton field slowly rolls from close to a maximum of its potential (i.e. the 'hilltop') towards its minimum. When the inflaton potential is associated with a phase transition, possible topological defects produced during this phase transition, such as domain walls, are efficiently diluted during inflation. It is typically assumed that they also do not reform after inflation, i.e. that the inflaton field stays on its side of the 'hill', finally performing damped oscillations around the minimum of the potential. In this paper we study the linear and the non-linear phases of preheating after hilltop inflation. We find that the fluctuations of the inflaton field during the tachyonic oscillation phase grow strong enough to allow the inflaton field to form regions in position space where it crosses 'over the top of the hill' towards the 'wrong vacuum'. We investigate the formation and behaviour of these overshooting regions using lattice simulations: Rather t...

We investigate the formation and behaviour of these overshooting regions using lattice simulations: Rather than durable domain walls, these regions form oscillon-like structures (i.e. localized bubbles that oscillate between the two vacua) which should be included in a careful study of preheating in hilltop inflation.

    The dynamic compaction of sand was investigated experimentally and computationally to stresses of 1.8 GPa. Experiments have been performed in the powder's partial compaction regime at impact velocities of approximately 0.25, 0.5, and 0.75 km/s. The experiments utilized multiple velocity interferometry probes on the rear surface of a stepped target for an accurate measurement of shock velocity, and an impedance matching technique was used to deduce the shock Hugoniot state. Wave profiles were further examined for estimates of reshock states. Experimental results were used to fit parameters to the P-Lambda model for porous materials. For simple 1-D simulations, the P-Lambda model seems to capture some of the physics behind the compaction process very well, typically predicting the Hugoniot state to within 3%.

    The Nigerian government has directed its Ministry of Mines, Power and Steel to assume responsibility for the exploration and exploitation of tar sands deposits in Bendel, Ondo and Oyo States. The directive resulted from a survey report by the University of Ife's geological consultancy unit on bituminous sand deposits in the area. The statement said the government was satisfied that there were large commercial quantities of the sands in the three states. The survey had reported that Nigeria could recover between 31 and 40 billion barrels of heavy crude from the tar sand deposits. Exploration for hydrocarbons is currently going on in Anambra and Lake Chad basins as well as the Benue Trough. Apart from the Nigerian National Petroleum Corporation, Shell Petroleum and Gulf Oil have begun exploration activities in the Ondo area. Meanwhile, Nigeria has had to import heavy crude from Venezuela, for processing at the Kaduna refinery.

    A new technique, the Solder Glass sand consolidation well completion method, has been developed which allows unlimited drawdown and improves productivity in wells completed in unconsolidated formations containing shales and clays. This technique eliminates the problems of sand production and fines migration by artificially consolidating a volume of reservoir sand near the wellbore. The consolidation is resistant to high temperature, chemical attack, and degradation resulting from high velocity fluid flow. Additionally, porosity and permeability in the consolidated volume of reservoir sand are improved as a result of irreversible dehydration of clays. 12 refs.

  11. Significant results of deep drilling at Elk Hills, Kern County, California

    Naval Petroleum Reserve 1 (Elk Hills) is located in the southwestern San Joaquin basin one of the most prolific oil-producing areas in the US. Although the basin is in a mature development stage, the presence of favorable structures and high-quality source rocks continue to make the deeper parts of the basin, specifically Elk Hills, an inviting exploration target. Of the three deep tests drilled by the US Department of Energy since 1976, significant geologic results were achieved in two wells. Well 987-25R reached low-grade metamorphic rock at 18,761 ft after penetrating over 800 ft of salt below the Eocene Point of Rocks Sandstone. In well 934-29R, the deepest well in California, Cretaceous sedimentary rocks were encountered at a total depth of 24,426 ft. In well 934-29R several major sand units were penetrated most of which encountered significant gas shows. Minor amounts of gas with no water were produced below 22,000 ft. In addition, production tests at 17,000 ft produced 46{degree} API gravity oil. Geochemical analysis of cores and cuttings indicated that the potential for hydrocarbon generation exists throughout the well and is significant because the possibility of hydrocarbon production exists at a greater depth than previously expected. A vertical seismic profile in the well indicated that basement at this location is at approximately 25,500 ft. Successful drilling of well 934-29R was attributed to the use of an oil-based mud system. The well took 917 days to drill, including 9,560 rotating hr with 134 bits. Bottom-hole temperature was 431{degree}F and pressures were approximately 18,000 psi. The high overburden pressure at 24,000 ft created drilling problems that ultimately led to the termination of drilling at 24,426 ft.

    The Dry Gas Zone in the Elk Hills field is comprised of fourteen separate productive horizons deposited in the MYA Group of the San Joaquin Formation of Pliocene Age. Eighty-six separate Reservoir Units have been identified within the interval over an area roughly ten miles long and four miles wide. One basal Tulare sand, the Tulare B, was also included in the geologic study. Five earlier studies have been made of the Dry Gas Zone; each is referenced in the Appendix of this report. Most of these studies were geologic in nature, and none provided in-depth reservoir analyses. This report is made up of ten (10) separate volumes which include: engineering text and exhibits (white dot); engineering data (black dot); geologic text and tables (green dot); structure and isochore maps (light blue dot); structural cross sections (dark blue dot); stratigraphic cross sections (brown dot); geologic data sheets -book 1 (yellow dot); geologic data sheets - book 2 (orange dot); geologic data sheets - book 3 (red dot); and geologic data sheets - book 4 (pink or coral dot). Basic production, injection, pressure, and other assorted technical data were provided by the US Department of Energy engineering staff at Elk Hills.

    We analyze the mesoscale structure of aeolian sand transport, based on a recently developed two-species continuum model. The calculated sand flux and important average characteristics of the grain trajectories are found to be in remarkable agreement with field and wind-tunnel data. We conclude that the essential mesoscale physics is insensitive to unresolved details on smaller scales and well captured by the coarse-grained analytical model, thus providing a sound basis for precise and numerically efficient mesoscale modeling of aeolian structure formation.

    A method for consolidating sand around a well, involving injecting hot water or steam through well casing perforations in to create a cement-like area around the perforation of sufficient rigidity to prevent sand from flowing into and obstructing the well. The cement area has several wormholes that provide fluid passageways between the well and the formation, while still inhibiting sand inflow.

  9. Analysis of Subsidence Data for the Big Hill Site, Texas

    SciTech Connect (OSTI)

    Bauer, Stephen J.

    1999-06-01T23:59:59.000Z

    The elevation change data measured at the Big Hill SPR site over the last 10 years has been studied and a model utilized to project elevation changes into the future. The subsidence rate at Big Hill is low in comparison with other Strategic Petroleum Reserve sites and has decreased with time due to the maintenance of higher operating pressures and the normal decrease in creep closure rate of caverns with time. However, the subsidence at the site is projected to continue. A model was developed to project subsidence values 20 years into the future; no subsidence related issues are apparent from these projections.

    The Idaho National Laboratory (INL) recently provided technical support for ongoing environmental remediation activities at the Shepley’s Hill remediation site near Devens, MA (Figure 1). The technical support was requested as follow-on work to an initial screening level radiation survey conducted in 2008. The purpose of the original study was to assess the efficacy of the INL-developed Backpack Sodium Iodide System (BaSIS) for detecting elevated areas of natural radioactivity due to the decay of radon-222 gases emanating from the underlying fracture sets. Although the results from the initial study were mixed, the BaSIS radiation surveys did confirm that exposed bedrock outcrops have higher natural radioactivity than the surficial soils, thus a high potential for detecting elevated levels of radon and/or radon daughter products. (INL 2009) The short count times associated with the BaSIS measurements limited the ability of the system to respond to elevated levels of radioactivity from a subsurface source, in this instance radon gas emanating from fracture sets. Thus, it was postulated that a different methodology be employed to directly detect the radon in the soil gases. The CR-39 particle track detectors were investigated through an extensive literature and technology search. The relatively long deployment or “detection” time of several days, as well as the sensitivity of the measurement and robustness of the detectors made the CR-39 technology promising for deployment at the Shepley’s Hill site.

    Sand pile formation is often used to describe stratified chaos in dynamic systems due to self-emergent and scale invariant behaviour. Cellular automata (Bak-Tang-Wiesenfeld model) are often used to describe chaotic behaviour, as simulating physical interactions between individual particles is computationally demanding. In this study, we use a state-of-the-art parallel implementation of the discrete element method on the graphical processing unit to simulate sand pile formation. Interactions between individual grains were simulated using a contact model in an Euler integration scheme. Results show non-linear self-emergent behaviour which is in good agreement with experimental results, theoretical work and self organized criticality (SOC) approaches. Moreover, it was found that the fully deterministic model, where the position and forces on every individual particle can be determined every iteration has a brown noise signal in the x and y direction, where the signal is the z direction is closer to a white noise spectrum.

    The properties of several tar sand asphalts prepared in past studies by several different investigators were compared with each other and with the properties of petroleum asphalts. These results were reviewed and discussed with regard to the potential use of tar sand bitumen in pavement applications. The data show that tar sand bitumen has good potential for use in highway pavements that meet today's performance specifications. No deficiencies in the tar sand asphalts were found that would be expected to seriously affect performance. On the other hand, the data indicate that some tar sand asphalts may have superior aging characteristics, being relatively resistant to oxidative age hardening compared with typical petroleum asphalts. Asphalt-aggregate mixtures prepared using two tar sand asphalts also showed acceptable strength properties and excellent resistance to moisture-induced damage.

    In August 2005, the U.S. Congress enacted the Energy Policy Act of 2005, Public Law 109-58. In Section 369 of this Act, also known as the 'Oil Shale, Tar Sands, and Other Strategic Unconventional Fuels Act of 2005', Congress declared that oil shale and tar sands (and other unconventional fuels) are strategically important domestic energy resources that should be developed to reduce the nation's growing dependence on oil from politically and economically unstable foreign sources. The Bureau of Land Management (BLM) is developing a Programmatic Environmental Impact Statement (PEIS) to evaluate alternatives for establishing commercial oil shale and tar sands leasing programs in Colorado, Wyoming, and Utah. This PEIS evaluates the potential impacts of alternatives identifying BLM-administered lands as available for application for commercial leasing of oil shale resources within the three states and of tar sands resources within Utah. The scope of the analysis of the PEIS also includes an assessment of the potential effects of future commercial leasing. This Class I cultural resources study is in support of the Draft Oil Shale and Tar Sands Resource Management Plan Amendments to Address Land Use Allocations in Colorado, Utah, and Wyoming and Programmatic Environmental Impact Statement and is an attempt to synthesize archaeological data covering the most geologically prospective lands for oil shale and tar sands in Colorado, Utah, and Wyoming. This report is based solely on geographic information system (GIS) data held by the Colorado, Utah, and Wyoming State Historic Preservation Offices (SHPOs). The GIS data include the information that the BLM has provided to the SHPOs. The primary purpose of the Class I cultural resources overview is to provide information on the affected environment for the PEIS. Furthermore, this report provides recommendations to support planning decisions and the management of cultural resources that could be impacted by future oil shale and tar sands resource development.

    3-D finite element analyses were performed to evaluate the structural integrity of caverns located at the Strategic Petroleum Reserve's Big Hill site. State-of-art analyses simulated the current site configuration and considered additional caverns. The addition of 5 caverns to account for a full site and a full dome containing 31 caverns were modeled. Operations including both normal and cavern workover pressures and cavern enlargement due to leaching were modeled to account for as many as 5 future oil drawdowns. Under the modeled conditions, caverns were placed very close to the edge of the salt dome. The web of salt separating the caverns and the web of salt between the caverns and edge of the salt dome were reduced due to leaching. The impacts on cavern stability, underground creep closure, surface subsidence and infrastructure, and well integrity were quantified. The analyses included recently derived damage criterion obtained from testing of Big Hill salt cores. The results show that from a structural view point, many additional caverns can be safely added to Big Hill.

    Screening tests of Sand Mantis candidate materials selected for erosion resistance have been completed. The results of this testing identified that over a relatively short period of operation (<1 hour), measurable erosion will occur in each of the candidate zoom tube materials given equal operating exposure. Additionally, this testing has shown that erosion of the rubber discharge hose directly downstream of the vehicle could be expected to limit the service life of the discharge hose. On the basis of these test results, SRNL recommends the following; {lg_bullet} redesign of critical system components (e.g., zoom tube, discharge hose) should be conducted to improve system characteristics relative to erosion and capitalize on the results of this testing, {lg_bullet} continued efforts to deploy the Sand Mantis should include testing to better define and optimize operating parameters, and gain an understanding of system dynamics, {lg_bullet} discontinue wear testing with the selected materials pending redesign of critical system components (1st recommendation) and inclusion of other candidate materials. The final selection of additional candidate materials should be made following design changes, but might include a Stellite alloy or zirconia.

    1989-04-04T23:59:59.000Z

    A process is described for upgrading a charge of a tar sand bitumen concentrate containing mineral matter including fine particles which comprises contacting the charge in a riser in the presence of a low boiling organic solvent diluent with finely divided attrition-resistant particles of a hot fluidizable substantially catalytically inert solid which is substantially chemically inert to a solution of mineral acid. The contact of the charge with the particles is at high temperature and short contact time to vaporize the high hydrogen containing components of the bitumen, the period of time being less than that which induces substantial thermal cracking of the charge, at the end of the time separating the vaporizing product from the fluidizable particles. The fluidizable particles now bear a deposit of both combustible solid, adherent particles of fine particles of mineral matter and metals. The particles of inert solid are passed with deposit of combustibles and fine particles of mineral matter to a regenerator to oxidize the combustible portion of the deposits, removing at least a portion of deposit of mineral matter and metals by removing the inert solid from the regenerator and contacting removed inert solid with a hot mineral acid, and recirculating fluidizable solid depleted at least in part of deposited mineral matter to contact with incoming charge of tar sand bitumen concentrate and diluent.

    This paper reports on the measurement of mass transfer rates for the extraction of bitumen from tar sands using organic solvents. The experiment was carried out in an agitated vessel using a six-blade turbine mixer on a laboratory scale. To facilitate the determination of absolute mass transfer coefficients, tar sands were specially prepared in the form of spherical particles so that mass transfer area can be computed. The variables investigated in the study included: (1) solvent type (kerosene, toluene, benzene), (2) stirrer speed, 25 rpm to 1000 rpm, and (3) particle diameter, 0.4 cm to 1.2 cm. The results indicated that solvency power varied markedly with the various solvents used and that high aromatic content promoted rapid dissolution when compared with paraffinic solvents. The mass transfer rates increased with increasing stirrer speed in accordance with the relationship: k {alpha} N{sup 0.56} where k is the mass transfer coefficient and N the stirrer speed. Increasing particle diameter also resulted in decreased mass transfer rates. The results were satisfactorily correlated in terms of a Frossling type equation, Sh {alpha} Re{sub p}{sup a}Sc{sup b}.

  2. Method and apparatus for hydrocarbon recovery from tar sands

    DOE Patents [OSTI]

    Westhoff, J.D.; Harak, A.E.

    1988-05-04T23:59:59.000Z

    A method and apparatus for utilizing tar sands having a broad range of bitumen content is disclosed. More particularly, tar sands are pyrolyzed in a cyclone retort with high temperature gases recycled from the cyclone retort to produce oil and hydrocarbon products. The spent tar sands are then burned at 2000/degree/F in a burner to remove residual char and produce a solid waste that is easily disposable. The process and apparatus have the advantages of being able to utilize tar sands having a broad range of bitumen content and the advantage of producing product gases that are free from combustion gases and thereby have a higher heating value. Another important advantage is rapid pyrolysis of the tar sands in the cyclone so as to effectively utilize smaller sized reactor vessels for reducing capitol and operating costs. 1 fig., 1 tab.

  4. Heats of dissolution of tar sand bitumen in various solvents

    SciTech Connect (OSTI)

    Ensley, E.K.; Scott, M.

    1988-05-01T23:59:59.000Z

    The dissolution of tar sand bitumen from a tar sand matrix was examined using three solvents: (1) dichloromethane, a polar-polarizable solvent; (2) toluene, a nonpolar-polarizable solvent; and (3) hexane, a nonpolar-nonpolarizable solvent. The dichloromethane had the highest dissolution energy, followed by toluene, with hexane having the lowest dissolution energy. These data were combined with heat of dissolution of recovered bitumen and heat of wetting of spent sand to calculate the bonding energy between bitumen and the mineral matrix. The interfacial bonding energy between tar sand bitumen and the mineral matrix was found to be in the region of 0 to 0.09 cal/g of bitumen, which is very small. This conclusion may find application in recovery of energy or bitumen from bitumen-wet tar sand deposits. 9 refs., 2 tabs.

  5. Acoustic sand detector for fluid flowstreams

    DOE Patents [OSTI]

    Beattie, Alan G. (Corrales, NM); Bohon, W. Mark (Frisco, TX)

    1993-01-01T23:59:59.000Z

    The particle volume and particle mass production rate of particulate solids entrained in fluid flowstreams such as formation sand or fracture proppant entrained in oil and gas production flowstreams is determined by a system having a metal probe interposed in a flow conduit for transmitting acoustic emissions created by particles impacting the probe to a sensor and signal processing circuit which produces discrete signals related to the impact of each of the particles striking the probe. The volume or mass flow rate of particulates is determined from making an initial particle size distribution and particle energy distribution and comparing the initial energy distribution and/or the initial size distribution with values related to the impact energies of a predetermined number of recorded impacts. The comparison is also used to recalibrate the system to compensate for changes in flow velocity.

  5. Investigation of tar sand and heavy oil deposits of Wyoming for underground coal gasification applications

    SciTech Connect (OSTI)

    Trudell, L.G.

    1985-02-01T23:59:59.000Z

    A literature review was conducted to identify and evaluate tar sand and heavy oil deposits of Wyoming which are potentially suitable for in situ processing with process heat or combustible gas from underground coal gasification (UCG). The investigation was undertaken as part of a project to develop novel concepts for expanding the role of UCG in maximizing energy recovery from coal deposits. Preliminary evaluations indicate six surface deposits and three shallow heavy oil fields are within 5 miles of coal deposits, the maximum distance judged to be feasible for UCG applications. A tar sand or heavy oil deposit in the northeast Washakie Basin is less than 250 feet above a zone of four coal seams suitable for UCG, and another deposit near Riverton appears to be interbedded with coal. Three shallow light oil fields found to be within 5 miles of coal may be amenable to application of UCG technology for enhanced oil recovery. Sufficient data are not available for estimating the size of Wyoming's tar sand and heavy oil resource which is suitable for UCG development. Additional investigations are recommended to more fully characterize promising deposits and to assess the potential resource for UCG applications. 54 refs., 10 figs., 2 tabs.

    The Naval Petroleum Reserve No. 1 (Elk Hills) is located in Kern County, California, and is jointly owned by the US Department of Energy and Chevron USA Inc. The Elk Hills Field is presently producing oil and gas from five geologic zones. These zones contain a number of separate and geologically complex reservoirs. Considerable field development and production of oil and gas have occurred since initial estimates of reserves were made. Total cumulative field production through December 1987 is 850 MMBbls of oil, 1.2 Tcf of gas and 648.2 MMBbls of water. In December 1987, field producing rates expressed on a calendar day basis amounted to 110,364 BOPD, 350,946 Mcfd and 230,179 BWPD from 1157 producers. In addition, a total of two reservoirs have gas injection in progress and four reservoirs have water injection in progress and four reservoirs have water injection in progress. Cumulative gas and water injection amounted to 586 Bcf of gas and 330 MMB of water. December 1987 gas and water injection rates amounted to 174 MMcfd and 234 MBWPD, into 129 injectors. In addition, a steamflood pilot program is currently active in the Eastern Shallow Oil Zone. Jerry R. Bergeson and Associates, Inc. (Bergeson) has completed Phase II of the Reservoir Analysis, Naval Petroleum Reserve Number 1, Elk Hills Oilfield, California. The objectives for this phase of the study included the establishment of revised estimates of the original oil and gas-in-place for each of the zones/reservoirs, estimation of the remaining proved developed, proved undeveloped, probable and possible reserves, and assessment of the effects of historical development and production operations and practices on recoverable reserves. 28 figs., 37 tabs.

    Yamazaki, T.

    1988-01-01T23:59:59.000Z

    Recently, oil sand bitumen has become the center of attention as a possible oil energy substitute for the future. Until now, the development of oil sand has been performed by surface miing and conventional steam injection, these methods are limited in respect to resource recovery. A more effective method needs to be developed utilizing in situ recovery. In this study, a new attempt is made for the purpose of enhancing the recovery of bitumen from oil sand by adopting the method of injecting high pressure steam and chemicals such as solvents, surfactants, and others.

  19. The potential use of tar sand bitumen as paving asphalt

    SciTech Connect (OSTI)

    Petersen, J.C.

    1988-01-01T23:59:59.000Z

    In this paper several research reports describing the preparation of potential paving asphalts from tar sand bitumen are reviewed and the results of the studies compared. The tar sand asphalts described in the studies were prepared from 1) hot water-recovered bitumen from deposits near San Luis Obispo, California (Edna deposits), and deposits near Vernal and Sunnyside, Utah; and 2) bitumen recovered from the Northwest Asphalt Ridge deposits near Vernal, Utah, by both in situ steamflood and in situ combustion recovery processes. Important properties of the tar sand asphalts compare favorably with those of specification petroleum asphalts. Laboratory data suggest that some tar sand asphalts may have superior aging characteristics and produce more water-resistant paving mixtures than typical petroleum asphalts.

    To date the commercial application of tar sand deposits in the United States has been limited to their use as paving materials for county roads, parking lots, and driveways because the material, as obtained from the quarries, does not meet federal highway specifications. The bitumen in these deposits has also been the subject of upgrading and refining studies to produce transportation fuels, but the results have not been encouraging from an economic standpoint. The conversion of tar sand bitumen to transportation fuels cannot compete with crude oil refining. The purposes of this study were two-fold. The first was to produce vacuum distillation residues and determine if their properties met ASTM asphalt specifications. The second was to determine if the distillates could serve as potential feedstocks for the production of aviation turbine fuels. The bitumen used for this study was the oil produced during an in situ steamflood project at the Northwest Asphalt Ridge (Utah) tar sand deposit. Two distillation residues were produced, one at +316/sup 0/C and one at +399/sup 0/C. However, only the lower boiling residue met ASTM specifications, in this case as an AC-30 asphalt. The original oil sample met specifications as an AC-5 asphalt. These residue samples showed some unique properties in the area of aging; however, these properties need to be investigated further to determine the implications. It was also suggested that the low aging indexes and high flow properties of the asphalts may be beneficial for pavements that require good low-temperature performance. Two distillate samples were produced, one at IBP-316/sup 0/C and one at IBP-399/sup 0/C. The chemical and physical properties of these samples were determined, and it was concluded that both samples appear to be potential feedstocks for the production of aviation turbine fuels. However, hydrogenation studies need to be conducted and the properties of the finished fuels determined to verify the prediction. 14 refs., 12 tabs.

    Laboratory cross-well P-wave transmission at 90 kHz was measured in a 61 cm diameter by 76 cm tall water-saturated sand pack, before and after introducing a non-aqueous phase organic liquid (NAPL) (n-dodecane). In one experiment NAPL was introduced to form a lens trapped by a low permeability layer; a second experiment considered NAPL residual trapped behind the front of flowing NAPL. The NAPL caused significant changes in the travel time and amplitude of first arrivals, as well as the generation of diffracted waves arriving after the direct wave. The spatial variations in NAPL saturation obtained from excavation at the end of the experiment correlated well with the observed variations in the P-wave amplitudes and travel times. NAPL residual saturation changes from NAPL flow channels of 3 to 4% were detectable and the 40 to 80% NAPL saturation in the NAPL lens was clearly visible at acoustic frequencies. The results of these experiments demonstrate that small NAPL saturations may be more easily detected with amplitude rather than travel time data, but that the relationships between the amplitude changes and NAPL saturation maybe more complex than those for velocity.

  5. Process for upgrading tar sand bitumen

    1989-02-14T23:59:59.000Z

    A process is described for upgrading a charge of a tar sand bitumen concentrate containing metal impurities, colloidal calcium-containing clay and water. It consists of contacting the charge in a riser contacting zone in the presence of a low boiling organic solvent with hot fluidizable attrition-resistant substantially catalytically-inert microspheres, which are 20 to 150 microns in diameter and are composed of previously calcined kaolin clay. The contact takes place at high temperature and short contact time, which permits vaporization of the high hydrogen containing components of the bitumen. The period of time is less than that which induces substantial thermal cracking of the charge. At the end of the time the vaporized produce is separated from the microspheres of calcined kaolin clay, the microspheres of calcined kaolin clay now bearing a deposit of combustible solid, metal impurities and adherent particles of colloidal calcium-containing clay originally contained in the bitumen concentrate, immediately reducing the temperature of the vaporized product to minimize thermal cracking and recovering the product for further refining to produce one or more premium products.

    The Main Body B, one of five large Stevens sand reservoirs at Elk Hills, occupies the eastern half of the 31S anticline. Early in the production history of this reservoir, the Elk Hills unit initiated peripheral water injection to maintain reservoir pressure. Water injection has proceeded at a rate approximately equal to the voidage created by oil and gas production and has moved water upstructure creating an oil bank. Bechtel Petroleum Operations Inc., the current unit operator, drills five to ten new wells each year to fully exploit this oil bank. In 1985, the unit added wireline pressure measurements to the open-hole logging programs of these infill wells for the purpose of evaluating the net effect of injection into and production from the Main Body B reservoir. A typical well provides the opportunity to obtain 8-10 pressures from the Main Body B. To date, the Unit has measured wireline pressures in more than two dozen wells. The wireline measurements have shown a broader than expected range of formation pressures (1,600 {plus minus} psi to 4,200 {plus minus} psi). The pressures show that this is a layered reservoir with little vertical pressure communication between some of the layers. In some parts of the reservoir, wireline pressures indicate horizontal continuity of the layers between wells and in other areas pressure differences between adjacent wells may indicate faults or cementation barriers. Permeabilities calculated from the sampling drawdown are the same order of magnitude as brine permeabilities obtained from core and show that higher-pressured layers of the reservoir have lower permeability. These observations fundamentally alter performance evaluation of the Main Body B waterflood.

    Horizontal drilling techniques have been used at the Elk Hills field, to more effectively produce the complex 26R reservoir. This Stevens zone reservoir of the Miocene Monterey Formation contains turbid sediments deposited in a deep-sea fan setting and consists of several distinct sandstone layers averaging 150 ft thick and usually separated by mudstone beds. Layers in the reservoir dip as much as 50{degree} southwest. An expanding gas cap makes many vertical wells less favorable to operate. Horizontal completions were thought ideal for the pool because (1) original oil-water contact is level and believed stable, (2) water production is low, (3) a horizontal well provides for a long production life; and (4) several sandstone layers can be produced through one well. For the first well, the plan was to redrill an idle well to horizontal along an arc with a radius of 350 ft. The horizontal section was to be up to 1,000 ft long and extend northeast slightly oblique to dip just above the average oil-water contact. The well was drilled in September 1988, reached horizontal nearly as planned, was completed after perforating 210 ft of oil sand, and produced a daily average of 1,000 bbl oil and 8 bbl of water. However, structural influence was stronger than expected, causing the horizontal drill path to turn directly updip away from the bottom-hole target area. The well also encountered variable oil-water contacts, with more than half the horizontal section possibly water productive. Geologic and drilling data from the first well were used for planning another well. This well was drilled in October 1989, and was highly successful with over 1,000 ft of productive interval.

    This report represents the work done during the year of May 8, 1987 to June 9, 1988. This year was the first year of a five-year program. The overall objective of the latter is to advance the technologies for recovering bitumen from the tar sands by thermal and water assisted extraction means and upgrading of bitumen to synthetic crude, and conversion of bitumens to specialty products such as asphalt and resins to levels where realistic evaluations of technical and commercial potential can be made. Additionally, it is desired to have the data at a level which is adequate for design of pilot plants of appropriate size deemed necessary for commercial scale-up of the various processes being studied. The main areas for studies covered in this report are modelling and optimization of the hydropyrolysis process for upgrading bitumens, bitumen recovery by pyrolysis of the circle Cliffs tar sands in a fluid bed, pyrolysis of Whiterocks tar sand in a rotary kiln, modelling of the combustor in the coupled fluidized bed with interbed heat transfer using heat pipes, development of superior diluents for use in the water extraction of Utah's tar sands, and fractionation and characterization of the bitumens from Asphalt Ridge and Sunnyside tar sands. 169 refs., 60 figs., 31 tars.

    Wind River Resources Corporation (WRRC) received a DOE grant in support of its proposal to acquire, process and interpret fifteen square miles of high-quality 3-D seismic data on non-allotted trust lands of the Uintah and Ouray (Ute) Indian Reservation, northeastern Utah, in 2000. Subsequent to receiving notice that its proposal would be funded, WRRC was able to add ten square miles of adjacent state and federal mineral acreage underlying tribal surface lands by arrangement with the operator of the Flat Rock Field. The twenty-five square mile 3-D seismic survey was conducted during the fall of 2000. The data were processed through the winter of 2000-2001, and initial interpretation took place during the spring of 2001. The initial interpretation identified multiple attractive drilling prospects, two of which were staked and permitted during the summer of 2001. The two initial wells were drilled in September and October of 2001. A deeper test was drilled in June of 2002. Subsequently a ten-well deep drilling evaluation program was conducted from October of 2002 through March 2004. The present report discusses the background of the project; design and execution of the 3-D seismic survey; processing and interpretation of the data; and drilling, completion and production results of a sample of the wells drilled on the basis of the interpreted survey. Fifteen wells have been drilled to test targets identified on the North Hill Creek 3-D Seismic Survey. None of these wildcat exploratory wells has been a dry hole, and several are among the best gas producers in Utah. The quality of the data produced by this first significant exploratory 3-D survey in the Uinta Basin has encouraged other operators to employ this technology. At least two additional 3-D seismic surveys have been completed in the vicinity of the North Hill Creek Survey, and five additional surveys are being planned for the 2004 field season. This project was successful in finding commercial oil, natural gas and natural gas liquids production on a remote part of the Uintah & Ouray Reservation. Much of the natural gas and natural gas liquids are being produced from the Wingate Formation, which to our knowledge has never produced commercially anywhere. Another large percentage of the natural gas is being produced from the Entrada Formation which has not previously produced in this part of the Uinta Basin. In all, at least nine geologic formations are contributing hydrocarbons to these wells. This survey has clearly established the fact that high-quality data can be obtained in this area, despite the known obstacles.

    Baylor University Center for Reservoir and Aquatic Systems Research (CRASR) has conducted a phased, comprehensive evaluation of Lake Whitney to determine its suitability for use as a regional water supply reservoir. The area along the Interstate 35 corridor between Dallas / Fort Worth Metroplex and the Waco / Temple Centroplex represents one of the fastest growth areas in the State of Texas and reliable water supplies are critical to sustainable growth. Lake Whitney is situated midway between these two metropolitan areas. Currently, the City of Whitney as well as all of Bosque and Hill counties obtain their potable water from the Trinity Sands aquifer. Additionally, parts of the adjoining McLennan and Burleson counties utilize the Trinity sands aquifer system as a supplement to their surface water supplies. Population growth coupled with increasing demands on this aquifer system in both the Metroplex and Centroplex have resulted in a rapid depletion of groundwater in these rural areas. The Lake Whitney reservoir represents both a potentially local and regional solution for an area experiencing high levels of growth. Because of the large scope of this project as well as the local, regional and national implications, we have designed a multifaceted approach that will lead to the solution of numerous issues related to the feasibility of using Lake Whitney as a water resource to the region. Phase IA (USEPA, QAPP Study Elements 1-4) of this research focused on the physical limnology of the reservoir (bathymetry and fine scale salinity determination) and develops hydrodynamic watershed and reservoir models to evaluate how salinity would be expected to change with varying hydrologic and climatic factors. To this end, we implemented a basic water quality modeling program in collaboration with the Texas Parks and Wildlife Department and the Texas Commission on Environmental Quality to add to the developing long-term database on Lake Whitney. Finally, we conducted an initial assessment of knowledge of watershed and water quality related issues by local residents and stakeholders of Lake Whitney and design an intervention educational program to address any deficiencies discovered. Phase IA was funded primarily from EPA Cooperative Agreement X7-9769 8901-0. Phase IC (USEPA, QAPP Study Element 5) of this research focused on the ambient toxicity of the reservoir with respect to periodic blooms of golden algae. Phase IC was funded primarily from Cooperative Agreement EM-96638001. Phase 1B (USDOE, Study Elements 6-11) complemented work being done via EPA funding on study elements 1-5 and added five new study elements: 6) Salinity Transport in the Brazos Watershed to Lake Whitney; 7) Bacterial Assessment; 8) Organic Contaminant Analysis on Lake Whitney; 9) Plankton Photosynthesis; 10) Lake Whitney Resident Knowledge Assessment; and 11) Engineering Scoping Perspective: Recommendations for Use.

  12. Investigation of guided waves propagation in pipe buried in sand

    The inspection of pipelines by guided wave testing is a well-established method for the detection of corrosion defects in pipelines, and is currently used routinely in a variety of industries, e.g. petrochemical and energy. When the method is applied to pipes buried in soil, test ranges tend to be significantly compromised because of attenuation of the waves caused by energy radiating into the soil. Moreover, the variability of soil conditions dictates different attenuation characteristics, which in-turn results in different, unpredictable, test ranges. We investigate experimentally the propagation and attenuation characteristics of guided waves in pipes buried in fine sand using a well characterized full scale experimental apparatus. The apparatus consists of an 8 inch-diameter, 5.6-meters long steel pipe embedded over 3 meters of its length in a rectangular container filled with fine sand, and an air-bladder for the application of overburden pressure. Longitudinal and torsional guided waves are excited in the pipe and recorded using a transducer ring (Guided Ultrasonics Ltd). Acoustic properties of the sand are measured independently in-situ and used to make model predictions of wave behavior in the buried pipe. We present the methodology and the systematic measurements of the guided waves under a range of conditions, including loose and compacted sand. It is found that the application of overburden pressure modifies the compaction of the sand and increases the attenuation, and that the measurement of the acoustic properties of sand allows model prediction of the attenuation of guided waves in buried pipes with a high level of confidence.

    Twenty-two sands in the Hewitt field have been flooded simultaneously by Exxon Co. U.S.A.'s Hewitt Unit, and a case history of the operations is detailed. A multiple sand waterflood project requires special optimization methods to improve oil recovery. Injection and production surveillance programs and optimization methods used are highlighted. These include injection wellbore design, injection distribution, production stimulation, polymer augmented injection, and infill drilling. Successful application of these techniques has increased ultimate recovery from this waterflood operation. 3 refs.

    Science graduate students from the University of California at Santa Cruz mentor a class of 7th graders from the Mission Hill Junior High School. The program`s purpose is: (1) to create a scientific learning community where scientists interact at different levels of the educational hierarchy; (2) to have fun in order to spark interest in science; and (3) to support girls and minority students in science. A total of seven mentors met with the students at least once a week after school for one quarter to tutor and assist with science fair projects. Other activities included a field trip to a university earth science lab, judging the science fair, and assisting during laboratory exercises. Graduate students run the program with minimal organization and funding, communicating by electronic mail. An informal evaluation of the program by the mentors has concluded that the most valuable and effective activities have been the field trip and assisting with labs. The actual {open_quotes}mentor meetings{close_quotes} after school did not work effectively because they had a vaguely defined purpose and the kids did not show up regularly to participate. Future directions include redefining ourselves as mentors for the entire school instead of just one class and better coordinating our activities with the teachers` curriculum. We will continue to assist with the labs and organize formal tutoring for students having problems with math and science. Finally, we will arrange more activities and field trips such as an amateur astronomy night. We will especially target girls who attended the {open_quotes}Expanding Your Horizons{trademark} in Science, Mathematics, and Engineering{close_quotes} career day for those activities.

    Jerry R. Bergeson and Associates, Inc. (Bergeson) has completed Phase 3 of the Reservoir Analysis, Naval Petroleum Reserve Number 1, Elk Hills Oilfield, California. The objective of this phase of the study was to establish the economic potential for the field by determining the optimum economic plan for development and production. The optimum economic plan used net cash flow analysis to evaluate future expected Department of Energy revenues less expenses and investments for proved developed, proved undeveloped, probable, possible and possible-enhanced oil recovery (EOR) reserves assigned in the Phase 2 study. The results of the Phase 2 study were used to define future production flowstreams. Additional production scheduling was carried out to evaluate accelerated depletion of proved developed reserves in the 29R, 31 C/D Shale and Northwest Stevens T Sand/N Shale Reservoirs. Production, cost and investment schedules were developed for the enhanced oil recovery projects identified in Phase 2. Price forecasts were provided by the Department of Energy. Operating costs and investment requirements were estimated by Bergeson. 4 figs., 48 tabs.

    This paper reports that the U.S. department of Energy has decided to ship 20,000 b/d of its Elk Hills field production in California to the Strategic Petroleum Reserve on the Gulf Coast. DOE says prices are too low to sell the high quality Elk Hills Stevens zone oil on the California market. It had warned local buyers it might divert the oil to the Gulf Coast. It says shipping the Elk Hills crude to the SPR site at Big Hill, Tex., will save $2/bbl under the price of comparable crude delivered there for storage in the SPR. Pipeline shipments are to begin June 1 and continue for 4 months, totaling about 2.4 million bbl. DOE may or may not continue the shipments, depending on results of the semiannual Elk Hills crude oil sale in September. Reductions in the existing 12 sales contracts will be prorated among buyers. The 20,000 b/d volume is the most that can be shipped from the West Coast to the Gulf Coast through available pipelines.

    This paper presents a methodology for assessing the phase composition and the results of structural stability tests of the sand-cast Mg–4Al–4RE alloy after annealing it at 175 and 250 °C for 3000 h. The microstructure was analyzed with optical, scanning electron, and transmission electron microscopy. The phase composition was determined with X-ray diffraction. The structure of the Mg–4Al–4RE (AE44) alloy is composed of large grains of ?-Mg solid solution, needle-shaped precipitates of the Al{sub 11}RE{sub 3}phase, polyhedral precipitates of the Al{sub 2}RE phase and Al{sub 10}RE{sub 2}Mn{sub 7} phase. After annealing at 175 °C for 3000 h, no changes in the alloy structure are observed, whereas after annealing at 250 °C the precipitates of the Al{sub 11}RE{sub 3} phase are found to be in the initial stages of spheroidization. The coarse-grained structure and unfavorable morphology of the intermetallic phases in the sand-cast AE44 alloy, which are caused by low solidification rates, result in low creep resistance up to 200 °C and low mechanical properties at ambient temperature and at 175 °C. - Highlights: • Complement the knowledge about the microstructure of Mg-Al-RE alloys. • Clarify the mechanism of formation of Mg17Al12 phase above 180 °C. • Applying a chemical dissolution of the ?-Mg in order to phase identification. • Applying a statistical test to assess the spheroidization of precipitates. • Quantitative description of microstructure of Mg-Al-RE alloys.

    This report addresses recent well integrity issues related to cavern 114 at the Big Hill Strategic Petroleum Reserve site. DM Petroleum Operations, M&O contractor for the U.S. Strategic Petroleum Reserve, recognized an apparent leak in Big Hill cavern well 114A in late summer, 2012, and provided written notice to the State of Texas as required by law. DM has since isolated the leak in well A with a temporary plug, and is planning on remediating both 114 A- and B-wells with liners. In this report Sandia provides an analysis of the apparent leak that includes: (i) estimated leak volume, (ii) recommendation for operating pressure to maintain in the cavern between temporary and permanent fixes for the well integrity issues, and (iii) identification of other caverns or wells at Big Hill that should be monitored closely in light of the sequence of failures there in the last several years.

    The Big Hill salt dome, located in southeastern Texas, is home to one of four underground oil-storage facilities managed by the U. S. Department of Energy Strategic Petroleum Reserve (SPR) Program. Sandia National Laboratories, as the geotechnical advisor to the SPR, conducts site-characterization investigations and other longer-term geotechnical and engineering studies in support of the program. This report describes the conversion of two-dimensional geologic interpretations of the Big Hill site into three-dimensional geologic models. The new models include the geometry of the salt dome, the surrounding sedimentary units, mapped faults, and the 14 oil storage caverns at the site. This work provides a realistic and internally consistent geologic model of the Big Hill site that can be used in support of future work.

    The growing interest in utilizing waste materials in civil engineering applications has opened the possibility of constructing reinforced soil structures with unconventional backfills. Scrap tires are a high-profile waste material for which several uses have been studied, including the use of shredded tires as backfill. A triaxial testing program was conducted to investigate the stress-strain relationship and strength of tire chips and a mixture of sand and tire chips. The test results and additional information from the literature were used in the numerical modeling of wall backfills, both unreinforced and reinforced with geosynthetics. The numerical modeling results suggest tire shreds, particularly when mixed with sand, may be effectively used as a backfill.

    To establish strength criteria of Big Hill salt, a series of quasi-static triaxial compression tests have been completed. This report summarizes the test methods, set-up, relevant observations, and results. The triaxial compression tests established dilatant damage criteria for Big Hill salt in terms of stress invariants (I{sub 1} and J{sub 2}) and principal stresses ({sigma}{sub a,d} and {sigma}{sub 3}), respectively: {radical}J{sub 2}(psi) = 1746-1320.5 exp{sup -0.00034I{sub 1}(psi)}; {sigma}{sub a,d}(psi) = 2248 + 1.25 {sigma}{sub 3} (psi). For the confining pressure of 1,000 psi, the dilatant damage strength of Big Hill salt is identical to the typical salt strength ({radical}J{sub 2} = 0.27 I{sub 1}). However, for higher confining pressure, the typical strength criterion overestimates the damage strength of Big Hill salt.

    The gas-producing gray sand, a dark gray to black, very fine-grained sand, occurs as 3 sand tongues in the lower member of the Smackover Formation in the subsurface of Bossier, Webster, Claiborne, and Lincoln parishes, Louisiana. A Flaser-bedded silty shale facies indicates deposition on a mid-tidal flat environment. Smackover deposition during the Jurassic in the study area was located on the gently dipping slope between a broad coastal shelf to the north and a basin to the south. The gray sand was deposited over the Norphlet formation and Louann salt before flowage and swelling of the Louann salt began. Uplift and swelling of the Louann salt later in the Jurassic created growing anticlines; sediment slumped off the structural highs of the growing salt anticlines into basinal muds and silts. The Smackover gray sand continues to challenge exploration geologists because of the lateral pinch out of its sand tongues. 11 references.

    Waterflood projects require an accurate knowledge of reservoir geometry and well-to-well continuity. However, sandstones with thin, multiple-pay zones can be extremely difficult to correlate with confidence. Two case studies of Pennsylvanian sandstones in Oklahoma illustrate how a model for the depositional history of such reservoirs can be an effective tool for determining reservoir continuity. In contrast, correlation criteria such as similar wireline log signatures and relative sand-body thicknesses are not reliable in many situations. In Southwest Logan field (Beaver County), 5 to 15-ft thick reservoir sands formed as shallow marine sand ridges. Their dimensions were approximated from height-to-width ratios of modern sand ridges. Then the reservoir sands were mapped using wireline logs and core data. Individual reservoir sands were approximately 1-2 km wide and stacked en echelon vertically. Thus, a line-drive waterflood pattern oriented parallel to the axes of the ridges is recommended. Tatums field (Carter County) consists of 5 to 50-ft thick sandstones deposited in various deltaic environments. Distributary channel sands have good continuity downdip, but are narrow and lenticular across depositional strike. Crevasse splay and other bay-fill sands were deposited marginal to the channels and are extremely discontinuous. This depositional model can be used to improve flood patterns for these sands, leading to improved sweep efficiency. In both examples, for effective mapping, the depositional facies models have been used to register reservoir quality and wireline log signatures.

    In the early phases of the product life cycle, the costs controls became a major decision tool in the competitiveness of the companies due to the world competition. After defining the problems related to this control difficulties, we will present an approach using a concept of cost entity related to the design and realization activities of the product. We will try to apply this approach to the fields of the sand casting foundry. This work will highlight the enterprise modelling difficulties (limits of a global cost modelling) and some specifics limitations of the tool used for this development. Finally we will discuss on the limits of a generic approach.

    In the past two years, Polycrystalline Diamond Compact Bits have gained acceptance in the United States with many spot applications in soft to medium hard formations. Diamond Compact Bits were chosen by Tenneco's Mid-Continent Division Drilling Department to be used at its South Graham Deese Sand Unit in Southern Oklahoma. Drilling in the field is complicated by a plunging anticline which has caused deviation problems in excess of 20. Previous wells were drilled in 24 days, excluding completion time, using conventional rotary bits and applying light bit weight to control deviation. Presently, by using a PDC bit, similar wells can be drilled in as little as 10 days.

    Evans, Carey and Crozier was given the task to conduct a Management Review of the Surface Operations of the 26R Reservoir in UONPR No. 1, Elk Hills field, Kern County, California. The MER strategy for this reservoir is to maintain pressure, and toward this end, gas injection volumes are scheduled to amount to 110% of calculated withdrawals. In spite of this, however, reservoir pressure continues to decline. The purpose of this study was, therefore, to determine if, and to what extent, field operating practices and accounting procedures may be contributing to this dilemma and to make appropriate recommendations pertaining to correcting any deficiencies which may have been found.

    The volume of future tight gas reserve additions is difficult to estimate because of uncertainties in the characterization and extent of the resource and the performance and cost-effectiveness of stimulation and production technologies. Ongoing R&D by industry and government aims to reduce the risks and costs of producing these tight resources, increase the certainty of knowledge of their geologic characteristics and extent, and increase the efficiency of production technologies. Some basins expected to contain large volumes of tight gas are being evaluated as to their potential contribution to domestic gas supplies. This report describes the results of one such appraisal. This analysis addresses the tight portions of the Eastern Greater Green River Basin (Sand Wash and Great Divide Subbasins in Northwestern Colorado and Southwestern Wyoming, respectively), with respect to estimated gas-in-place, technical recovery, and potential reserves. Geological data were compiled from public and proprietary sources. The study estimated gas-in-place in significant (greater than 10 feet net sand thickness) tight sand intervals for six distinct vertical and 21 areal units of analysis. These units of analysis represent tight gas potential outside current areas of development. For each unit of analysis, a ``typical`` well was modeled to represent the costs, recovery and economics of near-term drilling prospects in that unit. Technically recoverable gas was calculated using reservoir properties and assumptions about current formation evaluation and extraction technology performance. Basin-specific capital and operating costs were incorporated along with taxes, royalties and current regulations to estimate the minimum required wellhead gas price required to make the typical well in each of unit of analysis economic.

  6. Potential turbine fuels from western Kentucky tar sand bitumen

    The declining quality of petroleum is a particular problem for aviation turbine fuels. Since these fuels are required to meet stringent corrosion, thermal stability and purity specification, very little in the way of contaminants or heteroatoms can be tolerated. However, heavier and more sour crude supplied result in lower straight-run turbine fuel yields, higher sulfur contents, and higher aromatic contents. While all turbine fuels were originally prepared from high quality stocks by distillation, many commercial and military fuels now require hydrotreatment to meet specifications. The work described in this program extrapolates these present trends to very heavy feedstocks. Tar sands bitumen and heavy crude oils are low API gravity, high viscosity hydrocarbonaceous materials commonly exhibiting high levels of heteroatomic species, high metals content and high levels of asphaltenes, plus water and solids not readily separated by conventional technology without dilution. Tar sands bitumen is highly cyclic with many polycyclic rings and naphthenic constituents. Sulfur is primarily in thiophenic structures, with nitrogen included in the ring structure. Asphaltenes are in high proportion, with a large amount of sulfur, nitrogen and metallic inclusions. Each of these characteristics represent specific concerns to refiners.

    The existing Elk Hills facilities for fluid production consist of tank settings, gas and oil/water gathering pipelines, gas plants, compressor facilities, lease automatic custody transfer units which meter the crude oil going to sales, and natural gas sales meters and pipelines, water injection and source wells, and gas injection pipelines and wells. The principal safety concerns presented by operations at Elk Hills are fire, occupational safety and industrial hygiene considerations. Transportation and motor vehicle accidents are also of great concern because of the large amount of miles driven on more than 900 miles of roads. Typical operations involve hazardous materials and processing equipment such as vessels, compressors, boilers, piping and valves. The aging facilities, specifically the 35R Gas Plant (constructed in 1952) and many of the pipelines, introduce an additional element of hazard to the operations.

    This is an interim report on the present value of the net revenues from Elk Hills Naval Petroleum Reserve. GAO calculated alternative present values of the net revenues applying (1) low, medium, and high forecasts of future crude oil prices and (2) alternative interest rates for discounting the future net revenues to their present values. The calculations are sensitive to both the oil price forecasts and discount rates used; they are preliminary and should be used with caution. They do not take into account possible added tax revenues collected by the government if Elk Hills were sold nor varying production levels and practices, which could either increase or decrease the total amount of oil that can be extracted.

    The Elk Hills Naval Petroleum Reserve is located near Bakersfield, California and ranks seventh among domestic producing oil fields. In Feb. 1986 the Department of Energy awarded contracts to 16 companies for the sale of about 82,000 barrels per day of NPR crude oil between April and September 1986. These companies bid a record high average discount of $4.49 from DOE's base price. The discounts ranged from $0.87 to $6.98 per barrel. These contracts resulted in DOE selling Elk Hills oil as low as $3.91 per barrel. Energy stated that the process for selling from NPR had gotten out of step with today's marketplace. Doe subsequently revised its sales procedures which requires bidders to submit a specific price for the oil rather than a discount to a base price. DOE also initiated other efforts designed to avoid future NPR oil sales at less than fair market value.

    In previous work done on Utah's tar sands, it had been shown that the fluidized-bed pyrolysis of the sands to produce a bitumen-derived hydrocarbon liquid was feasible. The research and development work conducted in the small-scale equipment utilized as feed a number of samples from the various tar sand deposits of Utah elsewhere. The results from these studies in yields and quality of products and the operating experience gained strongly suggested that larger scale operation was in order to advance this technology. Accordingly, funding was obtained from the State of Utah through Mineral Leasing Funds administered by the College of Mines and Earth Sciences of the University of Utah to design and build a 4-1/2 inch diameter fluidized-bed pilot plant reactor with the necessary feeding and recovery equipment. This report covers the calibration and testing studies carried out on this equipment. The tests conducted with the Circle Cliffs tar sand ore gave good results. The equipment was found to operate as expected with this lean tar sand (less than 5% bitumen saturation). The hydrocarbon liquid yield with the Circle Cliffs tar sand was found to be greater in the pilot plant than it was in the small unit at comparable conditions. Following this work, the program called for an extensive run to be carried out on tar sands obtained from a large representative tar sand deposit to produce barrel quantities of liquid product. 10 refs., 45 figs., 11 tabs.

    The McGinness Hills geothermal system lies in a ~8.5 km wide, north-northeast trending accommodation zone defined by east-dipping normal faults bounding the Toiyabe Range to the west and west-dipping normal faults bounding the Simpson Park Mountains to the east. Within this broad accommodation zone lies a fault step-over defined by north-northeast striking, west-dipping normal faults which step to the left at roughly the latitude of the McGinness Hills geothermal system. The McGinness Hills 3D model consists of 9 geologic units and 41 faults. The basal geologic units are metasediments of the Ordovician Valmy and Vininni Formations (undifferentiated in the model) which are intruded by Jurassic granitic rocks. Unconformably overlying is a ~100s m-thick section of Tertiary andesitic lava flows and four Oligocene-to-Miocene ash-flow tuffs: The Rattlesnake Canyon Tuff, tuff of Sutcliffe, the Cambell Creek Tuff and the Nine Hill tuff. Overlying are sequences of pre-to-syn-extensional Quaternary alluvium and post-extensional Quaternary alluvium. 10-15º eastward dip of the Tertiary stratigraphy is controlled by the predominant west-dipping fault set. Geothermal production comes from two west dipping normal faults in the northern limb of the step over. Injection is into west dipping faults in the southern limb of the step over. Production and injection sites are in hydrologic communication, but at a deep level, as the northwest striking fault that links the southern and northern limbs of the step-over has no permeability.

    The Hill coefficient is often used as a direct measure of the cooperativity of binding processes. It is an essential tool for probing properties of reactions in many biochemical systems. Here we analyze existing experimental data and demonstrate that the Hill coefficient characterizing the binding of transcription factors to their cognate sites can in fact be larger than one -- the standard indication of cooperativity -- even in the absence of any standard cooperative binding mechanism. By studying the problem analytically, we demonstrate that this effect occurs due to the disordered binding energy of the transcription factor to the DNA molecule and the steric interactions between the different copies of the transcription factor. We show that the enhanced Hill coefficient implies a significant reduction in the number of copies of the transcription factors which is needed to occupy a cognate site and, in many cases, can explain existing estimates for numbers of the transcription factors in cells. The mechanism is general and should be applicable to other biological recognition processes.

    Today's commercially proved technology to recover oil from the Athabasca oil sands, as practiced by Suncor and Syncrude, involves two major operations, namely: separation of the bitumen from the sand and upgrading of the bitumen to refinery oil. Significant amounts of petroleum coke are produced during the bitumen upgrading process. Suncor burns the bulk of its petroleum coke in boilers to fulfill the energy requirements of the entire operation, still meeting government regulations restricting the amount of sulfur dioxide that can be released to the environment. In contrast, Syncrude is able to burn only 20% of its coke production because of high sulphur dioxide emissions from elsewhere in its operations. The boiler ash (Fly ash) which contains appreciable amounts of metals, such as vanadium, nickel, titianium, iron, aluminum and other elements, is collected in the boiler hoppers and cyclones of the petroleum coke fired steam generation plants. There has been relatively little effort made towards the understanding of the chemical or physical nature of these materials. Knowledge of the physico-chemical properties of these materials will be helpful in assessing their beneficiation and potential use as fuel or metallurigcal coke and the feasibility of extracting some metals, especially Ni and V. In this communication the authors report studies of acid demineralization as a means of reducing ash content of these materials for /sup 13/C NMR spectroscopic investigations.

    The deinventory process at Rocky Flats (RFETS) has included moisture content measurements of sand, slag, and crucible (SSC) materials by performing weight loss measurements at 210 degrees - 220 degrees Celsius on representative samples prior to packaging for shipment. Shipping requirements include knowledge of the moisture content. Work at the Savannah River Technology Center (SRTC) showed that the measurement at 210 degrees - 220 degrees Celsius did not account for all of the moisture. The objective of the work in this report was to determine if the measurement at 210 degrees - 220 degrees Celsius at RFETS could be used to set upper bounds on moisture content and therefore, eliminate the need for RFETS to unpack, reanalyze and repack the material.

    Model tests were performed at the Geotechnical Centrifuge Facility of Delft University of Technology, The Netherlands, to examine the mechanics of light nonaqueous phase liquid (LNAPL) movement in a partially saturated porous granular medium. The experiment simulated a 2D spill of LNAPL in an unsaturated sand prepared at two values of porosity. The duration of the centrifuge model tests corresponded to a prototype equivalent of 110 days. The choice of modeling a 2D flow together with the use of a transparent container enabled direct visual observation of the experiments. Scaling laws developed in connection with other centrifuge modeling studies were used to support the test results. Tests were conducted at two different centrifuge accelerations to verify, by means of the modeling of models technique, the similitude between the different experiments. The paper presents details of the experimental methodologies and the measuring techniques used to evaluate the final distribution of water and LNAPL content in the soils.

    The authors have investigated twenty three bitumen samples obtained using different separation methods such as: ultracentrifugation, Dean-Stark extraction, solvent extraction employing vigorous agitation, hot water separation and the Solvent Extraction Spherical Agglomeration technique. These samples were extracted from oil sand feedstocks of different grades, Suncor sludge pond tailings and mineral agglomerates obtained form the Solvent Extraction Spherical Agglomeration process. All of the bitumen samples were examined on a comparative basis using various analytical techniques. These included: fractionation into asphaltenes and maltenes: elemental analyses; molecular weight determination using vapour pressure osmometry and gel permeation chromatography, infrared, proton and /sup 13/C nuclear magnetic resonance spectroscopy. Proton /sup 13/C n.m.r. spectroscopic data were used to determine the distribution of various types of hydrogens and carbons in the samples. These data were also used to derive various molecular parameters in order to investigate average molecular structures of different bitumen samples and some of their asphaltene fractions.

    A method is described for hydroconversion of feedstocks consisting essentially of at least one heavy hydrocarbon oil selected from the group consisting of residue of petroleum oil distillation and the residue of tar sand bitumen distillation to enhance the recovery of 350/sup 0/-650/sup 0/F boiling product fraction. The method comprises treating such feed stock with hydrogen at superatmospheric pressure and in the presence of finely divided active hydrogenation catalyst in consecutive reaction stages. An initial reaction stage is carried out at a temperature in the range of 780/sup 0/-825/sup 0/F, and a subsequent reaction stage is directly carried out after the initial reaction stage at a higher temperature in the range of 800/sup 0/F-860/sup 0/F, the temperature of the subsequent reaction stage being at least 20/sup 0/F higher than that of the initial reaction stage.

    The relative permeability to fluids in hydrate-bearingsediments is an important parameter for predicting natural gas productionfrom gas hydrate reservoirs. We estimated the relative permeabilityparameters (van Genuchten alpha and m) in a hydrate-bearing sand by meansof inverse modeling, which involved matching water saturation predictionswith observations from a controlled waterflood experiment. We used x-raycomputed tomography (CT) scanning to determine both the porosity and thehydrate and aqueous phase saturation distributions in the samples. X-rayCT images showed that hydrate and aqueous phase saturations arenon-uniform, and that water flow focuses in regions of lower hydratesaturation. The relative permeability parameters were estimated at twolocations in each sample. Differences between the estimated parametersets at the two locations were attributed to heterogeneity in the hydratesaturation. Better estimates of the relative permeability parametersrequire further refinement of the experimental design, and betterdescription of heterogeneity in the numerical inversions.
